我的bitMapDownloaderTask是

private class BitmapDownloaderTask extends AsyncTask<String, Void, Bitmap> {

    private String url;
    private final WeakReference<ImageView> imageViewReference;

    public BitmapDownloaderTask(ImageView imageView) {
        imageViewReference = new WeakReference<ImageView>(imageView);
    }

    @Override
    protected Bitmap doInBackground(String... params) {
        url = params[0];
        InputStream is = httpRetriever.retrieveStream(url);
    if (is==null) {
            return null;
        }
    return BitmapFactory.decodeStream(new FlushedInputStream(is));
    }

    @Override
    protected void onPostExecute(Bitmap bitmap) {           
        if (isCancelled()) {
            bitmap = null;
        }

        addBitmapToCache(url, bitmap);

        if (imageViewReference != null) {
            ImageView imageView = imageViewReference.get();
            if (imageView != null) {
                imageView.setImageBitmap(bitmap);
            }
        }
    }
}

和我的httpRetriever.retrieveStream

      public InputStream retrieveStream(String url) {

    HttpGet getRequest = new HttpGet(url);

    try {

        HttpResponse getResponse = client.execute(getRequest);
        final int statusCode = getResponse.getStatusLine().getStatusCode();

        if (statusCode != HttpStatus.SC_OK) { 
            Log.w(getClass().getSimpleName(), "Error " + statusCode + " for URL " + url); 
            return null;
        }

        HttpEntity getResponseEntity = getResponse.getEntity();
        return getResponseEntity.getContent();

    } 
    catch (IOException e) {
        getRequest.abort();
        Log.w(getClass().getSimpleName(), "Error for URL " + url, e);
    }


    return null;

}

请帮忙......
